Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Drilling for Placer Gold The Keystone Drill, as universally used, is not an instrument of precision. Gold particles are not distributed with mathematical symmetry. One drill hole to an acre in ground that is 50 feet in depth only yields for examination part of the whole! Ordinary common sense and care on the part of the operator and panner are sufficient to insure acceptable field work. Meticulous precision or elaborate core measurements are generally absurd. For after the depths have been recorded and the gold weighed, there comes the calculation of the values of precious metal in great blocks of gravel. There is no fixed formula. The experienced Engineer, to whom such work should be entrusted, will compensate for high variations, for loose and swelling ground, for sand and clay, for rusty gold - and his calculations will of necessity contain approximations that eclipse minor errors of the field and nullify minute measurements. Indeed, field work with the Keystone Drill need not be conducted by men of profound skill. Just so the work is done in a consistent manner under the occasional eye of a competent engineer; just so the results are interpreted in the light of experience - then will the final figures carry the full weight of authority. There is no mystery about field work - and should there be, the following pages will clarify the mode of procedure.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Placer Gold Deposits of Nevada Following the discovery of placers at Gold Canyon, placer discoveries in Nevada were broadly in three periods: the 1860's to 1880's, when many small deposits throughout the State were discovered and sporadically worked and several large placers were discovered and extensively worked; the short period between 1906 and 1910, when very rich placers were dis covered at Lynn, Battle Mountain, Manhattan, and Round Mountain; the early 1930's, when economic conditions created by the depression caused a renewed interest in placer mining, and many individuals sought, and a few discovered, new placer areas throughout the State. The location of the placers described in this report is shown on plate 1. Very little factual information can be found about the early periods of placer mining in Nevada. For many placers, the only reports available are hearsay estimates of production and speculations about the extent of the placer ground based on remnants of placer pits, shafts, and other workings. Many of the placers said to have had a high production between 1860 and 1890 were worked by Chinese miners who came to Nevada dur ing the building of the railroads and stayed on to work at mining and other activities. The Chinese were reputed to be secretive with their earnings from the placers and did not ship the gold to the mint by Wells Fargo or other shippers. They worked the gravels very thoroughly in areas where American miners did not wish to expend great labor to win the gold. The placers in the Sierra and Spring Valley districts, Pershing County, were worked by Chinese miners; they have a very high estimated production before 1900 and a comparatively low known production since that time.
